Independent Sales Representative vs SDR or Outbound Agency

An independent sales representative sells your product or service as a self-employed contractor and earns commission on what they sell. They sit outside your payroll and usually get no salary. Many reps run the whole sale: they find prospects, pitch, negotiate and close, often for several non-competing companies at once.

If you are deciding whether to hire one, the choice comes down to this:

• Hire an independent rep when your offer already sells and the rep brings real relationships in your market.
• Hire an in-house SDR when you have a repeatable process and someone with time to manage that person every day.
• Use an outbound agency when you need the whole system built: the list, the messages, the sending and the reply handling.

Judge all three on one chain: what a qualified meeting costs you, how many of those meetings turn into signed clients, and what each new client costs in total. A rep is judged on the last number; an SDR and an agency on all three. Two legal questions sit underneath. Is the person really a contractor? And in the UK, what might you owe when the contract ends?

A disclosure before the comparison. My team runs cold email and LinkedIn outbound for B2B companies; we charge a monthly fee rather than commission, and the phone is not a channel we sell as a core service.

What does an independent rep actually do for you?

The rep runs their own operation, decides how to work, pays their own costs and invoices you for commission. You will also see sales agent, manufacturers' rep, 1099 rep (US) or commission-only agent (UK). The contract sets the scope; common duties include:

1. Finding and qualifying prospects in a territory or industry.
2. Presenting your product and handling objections.
3. Negotiating terms and closing the deal.
4. Looking after the account after the sale, if the contract says so.

An employed rep is someone you direct, train and pay through payroll. An SDR starts conversations and books qualified meetings for a closer, and is measured on those meetings. An independent rep is measured on closed revenue, so a rep's "leads" and an SDR's "meetings" never belong in the same spreadsheet column.

What does cost per meeting look like in each model?

Use two formulas, and never skip the second:

Cost per qualified meeting = everything the model cost you in a month / qualified meetings held that month

Cost per new client = the same monthly spend / new clients signed from those meetings

"Total" is where founders cheat themselves. The table shows what goes into the total in each model.

Pricing each model with your own numbers

Outbound agency. We charge from USD 3,000 (about EUR 2,500) a month, and companies that need more channels or more hands pay up to USD 10,000+. Software, data, mailboxes and sending domains sit on the client's own account, outside our fee.

When I plan a campaign, I expect roughly 1 reply per 100 people reached, sliding toward 1 in 200 when sending runs into the thousands per day. Between a tenth and a half of those replies become meetings.

Take a made-up month of 10,000 people reached (real volume depends on scope): that gives about 100 replies -> 10 to 50 meetings. Add an assumed USD 1,000 for tools and your time to the USD 3,000 floor, and a meeting costs USD 80 to USD 400. That is a planning range, not a quote or a result: it leaves out any setup fee and the slower first month.

In-house SDR. The total is salary, employer taxes and benefits, tools and data, plus the hours of whoever manages them. Ramp is the hidden part: in the first months you pay that full cost for very few meetings, so early cost per meeting runs far above the settled number.

How long is that ramp? Sloane Staffing, citing The Bridge Group's 2025 SDR research, puts average SDR ramp at 3.0 months, the lowest since 2010. The same article gives average SDR tenure as 1.9 years. It does not state the sample size. So about 3 months of a stay under 2 years go to ramp. Then you hire and ramp the next one.

I know of no single credible published cost per meeting for an in-house SDR; the published models swing widely, mostly on how many meetings a month they assume, which is why what one B2B meeting costs differs so much by channel. Put in your own salary offer and your own manager's hours.

Other agencies price differently, and what a lead generation agency costs depends on the model.

Independent rep. No credible published benchmark covers rep commission across industries; the rate is negotiated deal by deal. Manufactured products have rough ranges. RepHunter puts most independent rep commission there at 7% to 15%, and CaptivateIQ says manufacturing companies generally pay 3% to 15% of the gross sales revenue a rep brings in.

So price it from your own deal. As an illustration, a 10% commission on a USD 40,000 contract means each signed client costs USD 4,000 in commission, plus your training hours, plus any retainer spread across the clients signed. Set that against the cost per new client from the other two models, never against their cost per meeting.

Why the meeting number is only half the answer

Take one campaign we ran for an SEO agency in Switzerland. In 3 months, LinkedIn outreach from 2 accounts booked 215 sales calls as meetings, and 24 contracts were signed.

Read that funnel from the bottom. Each of the 215 meetings cost money to produce. The revenue came from the 24 that signed.

So the real comparison between a rep, an SDR and an agency is meetings that turn into revenue. I treat booking a call and closing a deal as separate jobs. When your close rate is weak, it only gets weaker as the number of calls grows. I would fix the sales process before buying another 100 meetings.

What has to happen after a call lands in the calendar matters as much as the booking, because the weeks after the call is booked decide whether it turns into a client.

To keep the comparison fair, use one definition of qualified for every model, count only meetings that took place, and run the second formula once deals have had time to close. My working benchmark is a closing ratio of 20% or better on held calls, though it varies by niche.

How are independent sales reps paid?

Rep pay is a contract you design, and these are the common structures:

On a long sales cycle, commission only is weaker than it looks. Zero fixed cost also means zero say over their week. A rep who waits months to be paid may give their time to the products that pay sooner.

In the UK, the Commercial Agents Regulations of 1993 contain rules on when commission is earned and on pay where nothing was agreed (legislation.gov.uk). Write it down so the defaults do not decide for you.

Before you agree a rate, settle these points in the contract:

1. The trigger that earns commission: signature, first invoice or cash received.
2. When it is paid, and against what statement.
3. Excluded accounts: existing clients, inbound leads, partners.
4. Territory and exclusivity, both ways.
5. Who owns CRM records, contact lists and message templates.

Rep, in-house SDR or outbound agency, which should you hire?

On the agency row: my team launches about 15 days after the contract is signed. What we need from you to start is usually a single 60-minute Zoom call and a few emails. When you pay for the domains and mailboxes yourself, ask for them in your company's name, so the sending channels stay with you if you leave.

Decision rules I would apply:

• If you cannot describe your buyer in one sentence, none of the three will save you. Pick one offer and one audience and commit to it for 12 months before you hire anyone.
• If you have a closer with free hours, buy meetings. That means an SDR or an agency.
• If nobody can take calls well, fix that first, or hire a rep who closes.
• If you would hire an SDR but nobody can manage them daily, an agency is the safer test. Booking meetings for you is what our appointment setting work does.

Cheap is not a filter. I see freelance SDRs and BDRs charge upfront for a playbook that is already out of date. A list a freelancer sold you cheaply shows it fast, in bounces and in emails nobody opens. Ask any candidate what they fix before they send.

Can a rep and an agency work together?

Yes, if you already have a good closer: the agency opens conversations in segments the rep does not cover, and the rep closes. If your team already sends and only needs better data, we sometimes supply custom lead lists as part of our B2B lead generation work.

One rule makes the hybrid work: I divide territories by account and by person, so two people never message the same buyer. The same rule applies when running an agency and an internal salesperson together.

Is an independent sales rep a contractor or an employee?

Status follows how the relationship works day to day, whatever the contract calls it.

In the US, the IRS puts the duty on the business: for each person it pays, it must decide whether they are employees or contractors. It groups the evidence into behavioral, financial and relationship categories, and says no set number of factors decides it (IRS).

Behavioral control is where sales setups usually slip. What counts is your right to direct how the work is done, even if you never use it. Instructions on when and where to work, which tools to use and what sequence to follow point to an employee. So does grading how the work is done. Ongoing training on your methods points the same way (IRS behavioral control).

So set hours, a mandatory script and weekly method training lean toward employment. Judging the rep only on closed deals can point either way.

In the UK, there are three statuses: employee, worker and self-employed. GOV.UK treats someone as self-employed when they run their own business and carry its success or failure, outside PAYE; quoting for work, invoicing and paying their own tax and National Insurance are typical signs. HMRC may reach a different view for tax than employment law does, and getting it wrong can mean unpaid tax and penalties (GOV.UK).

The middle status matters for commission-only deals. A worker has an arrangement to do work personally for a reward and can send a substitute only in limited cases. Workers are entitled to the National Minimum Wage and paid holiday (GOV.UK). Calling someone "commission only" does not switch those rights off.

Have a lawyer read the contract and how you actually manage the person; this is not legal advice.

What happens when a commission-only contract ends?

In the UK, the same 1993 Regulations also set minimum notice periods, give both sides the right to a signed written statement of terms, and decide payment when the agency ends (legislation.gov.uk).

They cover commercial agents as the regulations define them: self-employed agents with continuing authority to negotiate the sale or purchase of goods for a principal. A rep selling your equipment may be inside that definition; a rep selling consulting may not be.

Regulation 17 sets the money side (legislation.gov.uk):

• By default, the agent gets compensation, unless the contract says indemnity.
• Indemnity applies where the agent brought new customers or significantly grew business with existing ones, you keep benefiting substantially, and payment is equitable.
• The indemnity is capped at one year of the agent's average annual pay over the preceding five years.

What to document from day one:

1. Indemnity or compensation, chosen in writing.
2. Your customer list on the start date, so "new customers" can be measured later.
3. Monthly commission statements, signed off by both sides.
4. The notice terms, and how long commission continues on open deals.

Have a UK lawyer check the contract before you appoint the agent. In the US, commission owed after a rep contract ends is set by the contract and by the law of the state involved, so write post-termination commission into the agreement and ask a lawyer in the rep's state.

An agency ending is usually simpler. My team works with no minimum term and one month's notice.

How many meetings should you wait before judging?

Count from launch. Then judge each stage on its own clock.

With a rep, the first sign is a named opportunity. With an agency, it is a reply from the right person, and replies and the first booked meetings can come inside 30 days of launch. Signed contracts lag behind. A B2B buyer who meets you in month 1 may take 6, 9 or 12 months to decide, so a deal from that first month can easily close 4+ months later.

So the rule is: judge meetings after 3 months, and judge closing only once the meetings from those 3 months have been through one normal sales cycle.

Month one is usually the floor. For a UK social media marketing agency we worked with through LinkedIn, warm emails and cold email, booked sales calls went from 44 in month 1 to 57, then 68 in month 3, and reached 714 over 12 months. A verdict at the end of month 1 would have judged the weakest month of the three.

If a few thousand well-targeted contacts produce no conversations, I do not add volume. I go back to the offer and the list, because a funnel that fails small fails bigger. Inside the window, I keep testing messages and offers; the more variants we run, the sooner one wins.

Whichever model you pick, write the pay trigger and the end-of-contract terms down before month one, then judge it on signed clients, not on activity.
